Php Developer jobs in United Kingdom

We are a highly innovative and rapidly growing defence and technology company that design, develop, and deliver some of the world’s most advanced defence related training, products, and services.

We were recently crowned Employer of the Year at the British Ex-Forces in Business Awards 2023. We have been listed as one of the ‘100 Best Large Companies to Work For’ in the UK and Midlands by Best Companies several times as well as achieving ‘Best Companies 3 Star Accreditation’ and a rating of ‘world‑class’ for our employee engagement on a number of occasions. We are also proud to have been honoured with two Queen’s Awards for Enterprise in Innovation, for our next‑generation GECO military mission planning system.

As part of a unique and specialist defence company, our friendly team consists of experienced and highly capable individuals, working together with a mature ‘can do’ work ethic. Our central business functions are located in an easily accessible, bright and modern head office to the west of Lincoln, alongside our mission systems team, while the majority of our operational specialists are embedded alongside our Defence customers.

Mission Training Devices (MTD) are looking for a talented UI/UX‑focused software developer to join our growing team as we expand into new and exciting projects in synthetic training and simulation.

The focus will be developing software for synthetic training devices, primarily stand‑alone applications used in advanced training environments. The main focus will be mobile application development using .NET MAUI and the MVVM architecture, creating responsive, intuitive interfaces that make complex systems simple to use.

Working alongside backend developers, the successful candidate will take ownership of the user experience and interface design, shaping how users interact with our products and ensuring clean, efficient, and visually cohesive designs.

Experience with collaborative tools such as Azure DevOps, and GitHub is essential. MTD follows the SCRUM methodology, and previous Agile team experience will be advantageous.

This role is primarily home‑based, with most development work carried out remotely. Occasional travel to MoD Boscombe Down is required for in‑person meetings (typically once per month), with travel expenses reimbursed.

We are looking for a creative and detail‑oriented developer with a passion for building clean, user‑focused software.

You’re comfortable balancing form and function—making interfaces that are both practical and visually elegant.

• Develop and refine UIs using .NET MAUI (C# / XAML).
• Apply MVVM principles for clean, testable, and maintainable code.
• Collaborate with backend developers to integrate UI logic and data layers.
• Shape UX flow, layout, and visual structure of applications.
• Use Inkscape or similar tools to produce icons, overlays, and UI assets.
• Participate in code reviews and Agile sprints.

• Strong experience in .NET MAUI and MVVM UI development.
• Solid grasp of UX design principles and responsive layout design.
• Proficiency with XAML and data binding.

• Experience in Military Simulation or technical visualization.
• Familiarity with desktop UI development (.NET / WPF / WinUI).
• Background in vector graphics or interface design.

Due to the nature of elements of the role, the successful applicant must be a UK National and may be required to successfully complete National Security Vetting which may require criminal record, security service and credit reference checks; qualification will also normally require a minimum UK residency of at least 5 years

If you have the required background and are interested in joining a high‑performing team, supporting the delivery of exceptional award‑winning products and services to our customers, we would be delighted to hear from you. Please click apply and follow the instructions to upload your CV.
